Introduction to Extrusion granulator:
Extrusion granulator is also called double roller extrusion granulator, roll extrusion granulator, double roller granulator, Roller granulator. Extrusion granulator is a dry granulation process that uses pressure to agglomerate solid materials. By squeezing the material by two counter-rotating rollers, the rollers are driven by an eccentric sleeve or hydraulic system. When the solid material is squeezed, the air between the powder particles is first removed to rearrange the particles to eliminate the gaps between the materials.
Working principle of Extrusion granulator:
Through a certain amount of water or steam, the main working method is wet granulation of agglomerates. The basic fertilizer is fully chemically reacted in the cylinder after the humidity is adjusted. Under certain liquid phase conditions, with the help of the rotation of the cylinder, the squeezing force between the material particles can be formed into a ball.
Features and advantages of the Extrusion granulator process:
Double roller extrusion granulator is a fertilizer granulating equipment, using room temperature technology, no drying time, the output is 1-5 tons/hour, the equipment investment is small, the effect is fast, the economic benefit is good, the complete set of equipment is small in size, scientific, reasonable, and advanced in technology. , Energy saving, no waste, stable operation, convenient maintenance, and other advantages.
- Roll extrusion granulator is an extrusion type equipment. During operation, it realizes mass production through the continuous rotation of the motor and the continuous entry of materials. Therefore, it has the characteristics of simple operation and low energy consumption.
- The main parts such as the drum are all made of corrosion-resistant, abrasion-resistant, and impact-resistant new metal. The manufacturer of Tianci Heavy Extrusion granulator has also upgraded the frame parts. The bearing frame is made of high-quality anti-corrosion castings, which have good stability and can greatly improve the service life of rolling bearings and large shafts, the transmission part adopts a dual-input transmission mode.
- The roll extrusion granulator produced by Tianci not only improves the input power ratio but also ensures the lubrication and sealing performance of the transmission gear. It has the advantages of compact structure, good stability, excellent sealing performance, low noise, and convenient operation and maintenance. The Extrusion granulator It can automatically squeeze and granulate organic fertilizers. The density of the particles is large and uniform, the shape of the particles is good, the granulation efficiency is high, and the labor intensity is saved.
Precautions for using Extrusion granulator:
- Start and run the roll extrusion granulator, from slow to fast, check whether the operation is normal, and observe the working status of the instrument.
- Turn on the heater and heat up the machine head body. When the temperature of each part reaches the set requirement, it should be kept for about 40 minutes to make the temperature inside and outside the machine consistent.
- Sometimes it is necessary to change the porous plate, filter screen, and add enough lubricating oil. The porous plate must be cleaned after use before it can be used again.
- Start driving at a low speed, idling, check whether the screw is abnormal and the motor current and other instruments are overloaded, whether the pressure gauge is normal (the machine idling time cannot be too long, the shorter the better, in order to prevent friction between the screws and the screw and The friction and scratches of the barrel or the screw caused by the barrel, the low-speed operation time of the screw should not exceed three minutes).
